I am using Microsoft Outlook, and my PST file size has grown very large over time. I have already deleted many old and unnecessary emails and also emptied the Deleted Items folder, but the PST file size is still the same. I want to properly compress my PST file and recover the unused space that was created after deleting emails. My main concern is to reduce the file size safely without losing any important data or folders. Can anyone please suggest the best and safest way to compress a PST file and permanently clear unused space from deleted emails?

I was recently facing the problem of Outlook PST file size. Even after deleting emails, the size of the PST file was not reducing, due to which Outlook became very slow. After a lot of searching, I found DataVare Outlook PST Compact Expert Tool, and honestly it proved to be very useful. This tool safely clears the unused space created by deleted emails and compresses the PST file without any data loss. Its effect is clearly visible even on large PST files and Outlook's performance improves. The best part is that this tool comes with a simple interface, hence it can be used easily even without technical knowledge. If one wants to avoid Outlook PST size issue or corruption risk, then this tool is a practical solution.
